How can they be delivered from the life of self, who are not willing to abandon all their possessions? How can they believe themselves despoiled of all, who possess the greatest treasure under heaven? Do not oblige me to name it, but judge, if you are enlightened; there is one of them which is less than the other, which is lost before it, but which those who must lose everything have the greatest trouble in parting with.
